IMPROVEMENT IN SPIKE-MACHINES.

TO ALL WHOM IT MAY CONCERN;

Beit known that I, WILLIAM HAMILTON Snonnnnncnn, of Cincinnati, Hamiltoncounty, State of Ohio, have invented certain new and useful Improvementsin Spike-Machines; and I do herebyv declare the following-telic a full,clear, and exact description thereof, reference being had to theaccompanying drawings, making part of this specificati-on. Y i

My invention relates to anv improved means, device, or machine, wherebya number of spikes` are simultaneously out oi?, headedwup, and pointed',from a continuous bar of heated iron, at each stroke of the machine.

In the accompanying draivingsv Y I Figure 1 is a. partly-sectionizedfront elevation of a machine embodying my inventiomin the position inwhich the bar of iron (here represented by blue lines) is firstintroduced for cutting and'forming, this posit-ion being the extremityof the upward stroke ofthe machine.

y Figures 2 andA 3 exhibit the same views of vthe machine in subsequentpositions, g. 2 being the 'position just preparatory to heading up, thcspikes in this stage being cut oil` in lengths and forced down to aninclined bed, where they are forcibly hold for heading and sharpening.Fig. 3 is thc position of the machine after thespikes are headed up 'andpointed, the heading and sharpening being accomplished simultaneously.

` Figure 4 isa rear elevation of the machine, exhibiting the devices forthe movement or operation of the cutter-head. y

Figure 5 is a sectional plan, showing` the devices'for securing the barof iron sideways, and for forcing oli' tho spikes' from the machine whencompleted. v 4

The bed A of the machine is provided with tliostationary cutting-offsteelings a,'inclined beda, vertically dove-tailed back a, and slidesa,`on which the holding and throwing-cil` devices reciprocate.

` I3 is the vertically-reciprocatingputter-head, confined and slidingwithin thc dove-tails am of the back o".

The cutter-head has secured. toit a series of steelings, b, whichcombine the functions of both knives and clamps, and is operated bymeans of bain C, journalled in the back, al', cam D, on thedriving-shaft E, andc'onnections F G HAI J. v x I Fitted within thecutter-head B is the diagonally-slidingheading-block K, the shanks c ofwhich slide between the knives b. fThis/'block K'is opcratedby-means ofcam L, in shaft E, by the connectionl of swinging yoke M and Pitman N.y

The pointing 4of the spikes is accomplishedby means of the tumblers I),in the operation of which a.

rolling pressure is brought to bear upon the ends of the spikes,suiiicient to give them the sharpened ends,`thc.

pressure being against the knives which .are shaped, as shown, to formone side of the chamber.' The tumhlcrs rest in lpockets in the ends of'the vibrating-arms Q, and are operated by yoke M and connections R S T.

Y are sliding blocks, connected together by'means of links w w, andadaptedto receive a reciprocating motion through llever W andeam-groovcd'head X. The block U acts to carry forward andsecnre sidewaysthe bar of iron to be cut, and the block V, on thc return stroke, bymeans of prongs pushes out the completed spikes. The block U lisrecessed on its face, ata, to correspond with'similar recesses in thehed A, in order to gire space for vthe formation of the headsvcf thespikes.

Opration.

The bnr of iron isinscrted on the upward stroke of the machine, and iscarried forward and securely held sideways by means ol block U. Thecritter-.head B then descends, cuts oil` the iron in lengths, vandforces the blanks onto the inclined beds a', where they are securelyheld by the clamping-knives b. The heading-block 4Kis then pushedforward, and they tumhlers P moved to position, iig. 3, thissimultaneous action suhcing -to head up and point all thc'spikes in themanner shown in Iig. After this process, the cutter-head rises, theblock or side clamp retires, andthe block .V, by means of prongs rv,forces out the nished spikes. The bar of iron, blanks, and 'nishedspikes, are shown in blue, figs. 1, 2, and 3, and are also representedbyletter Z. The devices I R S T, I do not claim as entirely my owninvention.; they will form the subject of a. disi tuct and jointapplication hereafter.v

I claim herein 'as new, and of' my invention Y I 1. Theherein-'described series of dies a', cutters a b, and headers 7c, allarranged, relatively to the other parts of the machine, substantially asshown, and adapted to make more than one spike at cach operation from a.single bar or rod.

2. The arrangement, in th'e cutter-head B, of the head-Block K, headersk lc, and cutters b b, substantially in the nia-nner set forth. I

3. The arrangement of thel sliding block U,. links w w, head V,ejecting-rods a: :c z, lever W, and cam X, es described. v

' In testimony of which invention, I hereunto set my hand.
